This copier uses a stsndard agitating mechanism to keep the toner and
developer evenly mixed. It also helps agitate the developer to prevent clumps
from forming and helps create the triboelectric charge.
The developer on the rotating development roller is split into two parts by the
doctor blade [A]. The part that stays on the development roller [B] forms the
magnetic brush and develops the latent image on the drum.
The rest of the developer slides down the backspill plate to the paddle roller
[D]. The mixing vanes [E] move it slightly toward the rear (front: color
development unit) of the unit. Part of the developer falls into the auger inlet
and is transported to the front of the development unit (rear of the color unit)
by the mixing auger [F].
